PIANO-PLAYING EXPRESSION DEVICE.

` V Application led June 1.0,

#To all wliom, it may concern.'

Be it known that I, ROBERT GALLY, a

V citizen of the United States, residing at Ginthe bass (left) end piano containing the bellows; Fig. 2 a plan 3 an end view from of the bellows chest, with the connecting box removedand showing the.loudpedal pneumatic. j

A horizontal bellowschest 1 having a reservoir 2 and pumpers 3 and 4: combined view of same; Fig.

therewith, is suspended underneath and adl'jacent to the keybed 5 by a connecting box 6 at one end and by hangers 7 and 8 at .its otherlend. The hangers' are of dat metal bent at right angles at both ends of each, the upper bend being fastened to the under face of the keybed 5 by suitable screw or bolt 9, andV the lower coming under the bellowschest l, thus'acting as a supportof that end while the other end is being fastened, after which screws may be inserted to' hold the bellows chest more' securely. To give a firmer bearing for the hangers, the end of the bellows chest -is. finished witha piece ofl 'vice 12, 13, placed on top hardwood 1*.

The pumpers 3 and 4 are made on the un-'.

der face of chest '1. The loud pedal pneumatic 11 and valve-box 12 is shown on the left end space on top of said chest 1,but may be placedin other positions on .the top of said lchest 1 and give the benefit of a compact and direct arrangement. For convenience in removing and regulating the loud-pedalr deof chest 1, screwrods 13 are used with wing-nuts'or the like 14:, so that .the said devices or boxes may be easily attached. The loud-pedal valve-box 12 is placed on top and at the front of the bellows-chest 1 so that it is visible and accessible from the front when .in operation.

The rearfpart of the lower portion of the valve-box 12 is extended' to the rear and l Specication ofLettexs Patent- Patented-A131'. 1913.

Isla 'seal No. 'm2-,725,1

slanted downwardly,'an on top of this slant is fastened the lower stationary board 15 of the hinged pneumatic 11. I

From the moving-b ard 16 of loud-pedal pneumatic l1 is extended an armor finger 17 which acts downwardly on rod 18 which rests on end of a reverseflever 19, this lever 19 being pivoted on hanger-bloclc() fastened to the 'rear of the bellows chest 1. The other end of lever 19 has -apull wire 21 hung through a-hole in lever/ 9, with a regulating-nut 22 on the wire' 21 above `lever 19 to regulate the adjustment of the wire 21 to the bearing or screw 23 on lifter-rod 24 of the usual loud pedal action of the piano.

This arrangement of loud pedal parts combines cOmpaCtneSS, accessibility, ease of regulating, and general effectiveness. What I claim as my invention, is 1. In a player-piano: zontal bellows-chest suspended underneath land. adjacent to said keybed, a valve-box'A on'- the top face of and adjacent the frontof said chest, said box having a rearwardly extending part with its top slanting downwardly toits rear and toward the rear of said 'bellows-chest, and a hinged pneumatic positioned on the top of said slanting part of said box and with its Ahinge toward the front and itopen part at the rear edge of said bellows-chest,said valve-box having a valve controlling said pneumatic;

2. In a player-piano: a lreybed, a horizontal bellows-chest suspended from underneath .and adjacent to said keybed, a hinged pneumatic mounted on said bellows-chest with its open part at the rear edge of said bellowschest with its moving-board uppermost, a vertical rod from said moving-board downwardly, at the rear of said chest, a horizontal lever at bottom ofA said rod and connected to one end thereof, a center bearing intermediate the length of said lever, a pull wire 'extending down from the other end of said lever, a vertical lifting-rod of the piano devices, and a bearing on said lifter-rod, the lower end of said wire having engagement with said bearing.

3. In a player-piano: a keybed, a horizont'al bellows-cln'efstl suspended from underneath `and adjacent to said keyhed. a hinged pneumatic mounted on said lwllows-chcst with its open part at the rear edge of said bellowschest with its moving-board uppermost, a
